Version History
Software Version
Description
V1.05
Released first time
V1.06
Fix press STOP enter into sleep mode, and Beeper & LED warning.
V1.07
Support LTO battery, model is BMS24T
V1.11
Negative temperature can be measured.
V1.12
Add charge protection, Don’t charge under 2
℃
V1.13 (Hardware V2.2)
Add display module, improve voltage bar graph display, the lowest negative
20
can be detected
℃
V1.14 for LCD
Fix the charge and discharge WH bug
V1.15 for LCD
SOC can be setup to 0%
V1.16 for LCD
Start automatically on battery type and cell count setup interface, need not
press START button.
V1.21 for LCD
Fix a bug when display temperature difference at F.
Fix a bug on adjusting balance start voltage on LiTo battery
Add balance control item in storage status on Program Setup interface
---balance in Storage on or off
-- balance in Charge on or off
-- balance in Discharge on or off
Charge status
: charge current displayed over 1A
Discharge status
: discharge current display under-1A, such as -10A
Storage status
: current displayed between -1A ~ 1A
So current shunt and current sensor wire must be connected to BMS main unit.
Improved SoC of LiTo battery
V1.22 for LCD and V1.18
for main unit.
Improved SoC arithmetic
Fix a big when over discharge resume
Old version(main unit version V1.18, LCD unit V1.22) discontinued. The obvious different of old
and new main unit is new main unit with COM3 port. New main unit must fit with new LCD unit
(V3.0 to V3.03) that has different program.
